I've been distracted with other things so far this year. I apologize for the delayed response.
I had a CHTP GTC sell order fill on Monday. I may go short CHTP on an FDA approval.

Yesterday, I bought 5K EKSO at 2.95 average. I see RKW of Silicon Investor fame (aka James Silverman) is heavily involved. He is my most respected biotech investor by orders of magnitude. I would like to add shares at lower prices.
